A jigsaw is a tool used for cutting arbitrary curves, such as stenciled designs or other custom shapes, into wood, metal, or other material. It can be used in a more artistic fashion than other saws, which typically cut in straight lines only. Although a jigsaw can be used to cut arbitrary patterns, making a straight cut freehand is difficult even with a guide.
Traditional jigsaws are hand saws, consisting of a handle attached to a small, thin blade. The first jigsaw puzzles were made using this kind of unpowered saw. More modern jigsaws are power tools, made up of an electric motor and a reciprocating saw blade.
Big Boss, after forming and assuming command of the Militaires Sans Frontières, arranged to have a jigsaw blade made of steel wire concealed on his body, disguised as a snake-shaped scar similar to that of The Boss. He did this as a means to aid his escape in the event of enemy capture, should he be unable to utilize other means.
After escaping from an enemy detention center during the Peace Walker Incident in 1974, Big Boss told his lieutenant Kazuhira Miller that next time he would like something sharper for the next time he needs to escape, to which Miller jokingly asked if he wanted a diamond-bladed jigsaw and when the next time it would happen.
Behind the scenes
The Jigsaw is an item that appears in Metal Gear Solid: Peace Walker, which can be used by the player to escape from the prison cell. The Jigsaw's use is mandatory if the player fails to complete the QTE in the last portion of the previous mission. To obtain the Jigsaw, the player has to stand in front of a sink mirror and press the action button (the Triangle button for both the PlayStation Portable version and PlayStation 3 HD Collection version). Because of this special use, it cannot be found on Mother Base's R&D menu, either under the weapons category, the equipment category, or the special items category. If the player uses it during the level, the mission debriefing will include Miller and Snake referencing this means of escape, as well as explain that Big Boss's scar was in fact fake.
Even after using the Jigsaw, however, Big Boss's Naked and Swimsuit character models still feature the snake-shaped scar.
